A convenient route has been developed for mono and dioxygenated carbazole alkaloids from 1-oxotetrahydrocarbazoles. The key step of the synthetic route is the aromatic process of 1-oxotetrahydrocarbazoles using molecular iodine. To our knowledge, this is the first report to manifest a direct synthesis of clausine E, mukonine, mukoeic acid and mukoline, from readily available ester-containing building
对于1-氧四氢咔唑的单和双氧化咔唑生物碱,已经开发了一种简便的方法。合成路线的关键步骤是使用分子碘进行的1-氧四氢咔唑的芳香化工艺。据我们所知,这是第一个通过费歇尔-保时捷方法从易得的含酯结构单元中直接合成克劳斯碱E,鼠李糖碱,鼠李酸和鼠李碱的报告。
